please guys answer fastly with full explanation.

Answer 1

total no of possible outcome =4
total no of probable outcome =3
probability =3/4
hope it help u miss sneha

Answer 2

∫Total possible outcomes =  {H, H} {H, T} {T, H} {T, T}

→ n.o of possible outcomes =  4

                                                                                                           

∫total outcomes she get atleast one head =   {H, H} {H, T} {T, H}

→ n.o of outcomes  one head = 3

∫ she get atleast one head ∫

$= \frac{number of outcomes where she get atleast one head }{n.o of possible outcomes} \\ \\ \\  = \frac{3}{4}$
